again. Repeat this for all the open images; a chime will sound when you
have gone through all the open images. (If you use the Manual 2 stars
align mode, then select another alignment star in the first image displayed
after you hear the chime).
7. If you find an image that looks poor, you can reject it by clicking the Reject
Image button. Use the Next Image (and/or Previous Image) button to
continue going through the open images after an image is rejected.
At least one image must be used as the reference image for the stacked
images to be overlaid upon. The default uses the first image for the reference
image. If you reject the first image or otherwise want to use another image as
the reference, click the Set As Reference button. If the image currently cho-
sen as the reference is rejected from the stack, you will not be able to Overlay
All Images.
8. Now, click the Overlay All Images button. All of the selected images will
stack on top of each other to form one resultant image. Click OK
Figure 18. The Combine
Images window allows

resultant image.
